New issue 1284 by [email protected]: --print_code_stubs crashes v8 shell
after isolates
http://code.google.com/p/v8/issues/detail?id=1284
run shell_g --print_code_stubs
It crashes because during isolates initialization some stubs are generated
and therefore V8 attempts to print them, referencing null pointer:

Where data (DeoptimizerData*) is null.
This looks like order of initialization issue where inside Isolate::Init
builtins::Setup is called (where this crash happens) and only later
deoptimizer_data is initialized. However, the issue may run deeper.
